SASH-FASTEN ER.

SPECIFICATION forming part Of Letters Patent NO. 426,303, dated April22, 1890.

Application led December 4:, 1889. Serial No. 332,549. (No model.)

T0 all whom. it may concern:

Be it known that I, FRANCIS P. MeGovERN, a citizen of the United States,residing at Conshohocken, in the county of Montgomery and State ofPennsylvania, have invented a new and useful Improvement inSash-Fasteners, which improvement is fully set forth in the followingspecification and accompanying drawings.

My invention consists of improvements in a sash-fastener adapted to lockupper and lower sashes to each other and to the windowframe, as will behereinafter fully set forth and definitely claimed.

Figure l represents a perspective view of a sash-fastener embodying myinvention. Figs. 2 and 3 represent longitudinal sect-ions of portionsthereof. Figs. 4t and 5 represent sections on lines, respectively, 'y yand o; o3, Fig. 2, on an enlarged scale.

Similar letters of reference indicate corresponding parts in the severalfigures.

Referring to the drawings, A and B represent two boxes, which areconnected by a plate C, so that they extend at a right angle to cachother, the box A being located on the top of the meeting-rail of thelower sash, and the box B the front thereof, said boxes being iirmlysecured to the meeting-rail and each containing a bolt, the bolt D ofthe upper box being adapted to engage with a perforated or recessedplate E, secured to the side rail of the upper sash, and the bolt F ofthe lower box being adapted to engage with a perforated or recessedplate G, secured to the side stile or rail of the window-frame, it beingnoticed that the bolt D locks the two sashes to each other, and the boltF locks said sashesto the window-frame, thus doubly fastening the sash.

In Fig. 1 the bolt D is shown with a knob, and in Fig. 2 with a hook,either adapted to withdraw the bolt, when so required, without, however,effecting the operation of the device.

The upper bolt is held in engagement with the plate E by means of aspring H, which bears against one end of the box A, and a shoulder J atthe back of the head of the bolt.

A portion of the bolt F is screw-threaded, as at K, and thecorresponding portion of the interior of the box B, through which saidbolt passes, is also threaded, whereby the bolt may be advanced andreturned by rotating the same, and said bolt cannot be shot back by animplement inserted between the box B and plate G.

The box A has portions of its upper part and ends separated from theremaining parts, forming a cap L and tongues M, the latter being at theends of the cap and of dovetailed form to fit or engage dovetail groovesN in the end walls of the box, said cap and tongues being readilyremovable from the contiguous parts of the box by motions in thelongitudinal direction thereof. It will be seen that primarily the capmay be slid out at the nose end of the box, thus uncovering the top ofsaid box, and likewise the ends thereof, owing to the connection of thetongues M with said cap. The spring ll and bolt D may now be inserted inposition in the box, after which the cap and tongues are restored, thusclos# ing the top and ends of the box and retaining the bolt and springin position, it being noticed that the under portion of the tongues andfront end of the upper portion of the contiguous wall are recessed toreceive the adjacent portion of the bolt and permit the movements of thelatter, it being also noticed that the spring occupies a recessed orreduced portion of the bolt D, thus decreasing the thickness of the boxA.

The dovetailed tongues M are held tightly in the dovetailed grooves N,whereby displacement of the cap is prevented; but they may be forciblydriven from their position,where by access may be had to the bolt andspring when so required. l

It is evident that the 'screw-bolt F may be held disengaged from theplate G by properly rotating the same, the spring-pressed bolt D thenbeing employed for ordinarily fastening the two sashes; but at night, orwhen the room is unoccupied, the bolt F is properly 10- tated, so thatthe two sashes as fastened by the bolt D may be said to be screwed tothe window-frame, thus rendering the fastening doubly reliable in itsaction.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

l. A sash-fastener consisting of two bolts and boxes therefor, saidboxesbeing connected at an angle, whereby one box occupies the top of ameeting-rail and the other box occupies the front thereof, substantiallyas described.

2. A sash-fastener consisting` of two boxes at an angle to each otherand at different ele- 5 vations, one box containing a spring-pressedbolt and the other box containing @screwbolt, said bolts engaging withplates, respectively, on the sash and frame, substantially as described.Y

3. In L Windmwfatstener, t bolt, a; box con- Io taining the sinne havinga dovetail groove therein, and a' removable cap having inclined sides tot said groove, substantially as described.
